13 Claims.

This invention relates to railway car moving apparatus, and particularlythe invention relates to apparatus of the aforesaid character adaptedfor pushing or imparting relatively slow movement to railway carswhile'such cars are located on sidings at loading platforms, or in andabout manufacturing plants, or in other similar situations Where a,conventional switching locomotive is not readily available.

Where such movements of railway cars have been required it hasheretofore been customary to utilize a car pusher in the form of anelongated hand lever having a forward operating end or elementassociated therewith and adapted to be wedged into the acute angularspace between a car wheel and the rail upon which such wheel issupported, and by downward movement of the hand lever, the operatorcauses the operating end or element of the car pusher to impart anupward and forward force to the wheel to thereby cause forward rollingmovement of the wheel. The operator then raises the hand lever andforces the forward element of the car pusher forwardly along the rail soas to reestablish the operative relation between the car pusher and thecar wheel, and by another downward movement of the operating handleanother forward rolling force may be applied to the wheel. Thus byrepeated up and down movements of the operating handle, coupled withappropriate forward movements of the pusher to repeatedly reestablishthe operative relationship with the wheel, an operator with theconventional car pusher is able to attain the desired movements of arailway car, but such movements of the railway car are relatively slow,and involve extreme physical exertion, particularly where the cars areheavily loaded or where the siding or track is inclined or curved.

In view of the foregoing it is the primary object of the presentinvention to simplif the p shing or moving of railway cars on sidingsand the like, and to enable such car movements to be attained rapidlyand with very little physical exertion. Further and related objects ofthe invention are to-enable a car pusher to apply a continuous forwardrolling force to the wheel of a car so as to attain a continuous forwardmovement of the cars, to automatically maintain such a car pusher in anoperative relationship with respect to the carwheel as the forwardrolling movement of the ear wheel progresses, and to enable such a carpusher to be embodied in a relatively portable form that includes powerdriven means for applying the requisite forces between the ear wheel.and the rail.

Other and further objects of the present invention will be apparent fromthe following description. In the accompanying drawings which, by way ofillustration, show a preferred embodiment and the principle thereof andwhat I now consider to be the best mode in which I have contemplatedapplying that principle. Other embodiments of the invention embodyingthe same or equivalent principle may be used and structural changes maybe made as desired-by those skilled in the art without departing fromthe present invention and the purview of the appended claims.

In the form chosen for disclosure herein the invention is embodied in apower operated car moving apparatus or car pusher l0 that is portable incharacter and is adapted to be supported and guided on a railway rail Rso as to be disposed in the rearwardly facing acute angular spacebetween a rail R and the tread Tof a wheel W supported on the rail, andwhen the car pusher I0 is the other side of thus positioned it iseffective to impart forward rolling forces to the wheel'Wto therebycause the desired forward movement of the railway car that is carried inpart by such wheel. The car pusher ID has its operating mechanismscarried by a main frame I2 which, as shown in Fig. 1, is generallytriangular in side elevation so as to thereby enable the frame tobeaccommodated in the acute angular space that is available between therail R. and the wheel W, and the narrow forward end or ex.- tension IZFof the frame [2 serves as a mounting for a force applying or tractiveunit [4 for operative engagement with the wheel W and the rail R toimpart forward rolling movement to the wheel W and at the same timeadvance the car pusher l0 along the rail to maintain the desiredoperative. relationship with the wheel W. The forward end of the frameI2 is supportedand-guided on the rail R by elements of the tractiveunit, as will hereinafter become evident, while the rear end of theframe l2. is supported on the rail-R by a roller l6 disposed near therear end of the frame, and in the use of the car pusher I0, its positionand operation may be controlled and governed by the operator by means ofa handle l8 that extends upwardly and rearwardly from the frame l2 sothat it may be grasped and held by the operator during operation of thecar pusher.

In the present instance the tractive unit l4 of the car pusher ID isdriven by power means in the form of an electric motor that is mountedon one Side of the frame [2 as to project laterally therefrom, and theweight of the motor 20 is substantially counterbalanced by a lateralextension 22, that projects from the opposite side of the frame, asshown in Figs. 3 and 5, and which serves as a housing for a part of thepower transmission means between the motor 2!] and the tractive unit I4. In practice the electric power for the motor 20 is supplied by anelectric cord 24 that extends into the end of the handle l8 as shown inFig. 1, and the handle is preferably tubular in character so that thecord 24 may extend downwardly therethrough to a point adjacent the frame12 where it is led outwardly through a side opening 26 and is connectedto the motor 20. Near the upper end of the handle I8 a control switch 28is mounted inside of the handle, and is interposed electrically in thecord 24, and by manipulation of a projecting switch handle 28A, the usermay start and stop the motor 20 as required in the use and control ofthe car pusher.

As will be evident in Figs. 3 and 5, the frame I2 is constructed in theform of a sectional housing that affords an enclosure as well asmounting means for the elements of the transmission gearing between themotor 20 and the tractive unit 14, and to this end, the frame l2comprises a main housing section |2A having a side wall I23 and edgeflanges or walls 120 about the edges thereof to thereby define a gearchamber !2D that is closed by a side or cover plate IZE. Fastening bolts29 are extended through the housing section I 2A and into the coverplate IZE to secure the same in position on the section HA. The mainhousing section [2A has a projecting mounting base or flange 30 extendedfrom the outer side thereof to receive and interlock laterally with theflanged end of the casing of the motor 20, and fastening bolts 32extended through the motor casing are threaded into the flange 30 so asto hold the motor 26 in place on the housing section I2A,

When the motor 20 is thus secured in place the motor shaft 29A extendsthrough an opening 34 in the side wall I 2B of the housing section l2Aso that a drive pinion 36 on the end of the motor shaft 20A is disposedwithin the gear chamber I2D. The pinion 36 that is thus located withinthe gear chamber I2D is operative to drive a speed reducing and motiontransmitting gearing that is housed in part within the gear chamber I2Dand in part within the extension 220i the frame l2, and such gearingterminates in a drive shaft 40 that is supported in the extension 22 andis operatively connected to the tractive unit l4 in a driving relationas will hereinafter be described in detail. In effecting such drivingconnection between the drive shaft 45 and the tractive unit I4, thedrive shaft 49 is so disposed that a splined end 46A thereof is locatedwithin the forward frame extension IZF and outside of the forward edgewall IZC of the housing section I2A, and to afford such a location forthe shaft 40, the extension 22 is formed on the'cover plate IZE in aforward position as shown in Figs. 3, 5 and 6. Thus, the extension 22,as herein shown, comprises a first tubular section 22A opening throughthe plate I 2E into the gear chamber [2D and a second tubular section223 formed on the plate I 2E so as to open through the plate at a pointforwardly of the forward edge wall [20 of the housing, and theprojecting ends of the tubular sections 22A and 22B are closed by ahollow and generally cupshaped cap 220 that abuts a flange 22F formedabout the ends of the tubular sections 22A and 22B, and the cap 220 isheld in place by screws 42.

The drive shaft 46 is rotatably supported in the tubular section 223 bya bearing sleeve 44 and near the end thereof a gear 45 is fixed on theshaft 46 so as to be disposed within the cap 22C, the extending end 40Bof the shaft 46 being supported in the cap 220 by a bearing sleeve 46.The tubular section 22A serves to support a transmission shaft 56 bymeans of a bearing sleeve 52, while a bearing sleeve 54 in the cap 220rotatably supports the end 50B of the shaft 56, and between the twobearings 52 and 54, the shaft 56 is splined as at- 50A and has a gear 55engaged with the splines 56A and housed within the cap 220. The gears 45and 55 are operatively connected by an idler gear 51 disposed within thecap 22C and fixed on a supporting stub shaft 58. One end of the stubshaft 58 is rotatably supported on a bearing sleeve 51 in the cap 220,while a bearing sleeve 60, mounted in a web 22W that connects the endsof the tubular sections 22A and 22B, serves to support the other end ofthe stub shaft 58.

The transmission shaft 50 is arranged to extend into the gear chamberI2D, and within this chamber a gear 65 is fixed so that a speed reducinggearing may be afforded within the chamber 12D between the drive pinion20A and the gear 55. Such speed reducing gearing is in the present caseafforded by a series of interconnected gears and pinions supportedwithin the housing or chamber I2D by three parallel shafts 65, 6? and68, the opposite ends of which are rotatably supported by appropriatebearings, such as bearing bosses 69, provided on the side wall I23 and.the cover plate I2E. The shaft 66 has a large gear 66G and a smallpinion 66P fixed thereon so that the gear 66G is meshed with the drivepinion while the shaft 61 has a large gear MG and a small pinion 6IPfixed thereon so that the gear 61G meshes with the pinion 66F.Similarly, the shaft 68 has a large gear EEG and a small pinion 68Ffixed thereon, and the gear 68G is meshed with the pinion 67F while thepinion 68P is meshed with the gear 65. Thus a substantial gear reductionis afforded whereby the drive shaft 46 is driven at a slow speed that issuitable for operation of the tractive unit l4.

As hereinbefore pointed out, the tractive unit I4 is supported by theforward extension 12F of the frame l2 of the device, and as will beapparent in the drawings, the extension I2F of the frame is sectional incharacter and is formed in part by a forward extension of the coverplate iZE of the gear housing. Thus this forward extension IZF acts asone bearing plate and serves as a support for a parallel but spacedbearing plate 1:"! so that the operating or force applying elements ofthe tractive unit l4 may be supported between such bearing plates. Theforce applying elements of the tractive unit M are in the present caseafforded by three toothed wheels H, 12 and 73 that are rotatably mountedbetween the bear ing plates [2F and 10, and the two bearing plates resenamhlvreleied-H31 eams such e he n, PQsition .therebetw'enl wheels obe 291 the. towa d e d nd "there stwe l th geed. reamed which fasteningbolts .11 are extended'whilead jacentthe forwardfwall {2C cr ngehousing; the plates lZ F and m have .o p'osea upunibosses IS arrange'dso their inner. endsf abut each other; and a fastening bolt T9'ispassedthrough the bosses 18 to secure the plate 'Hl 'on'the' plateMP.

The mounting space'that'is thus afforded between the plates [2F andlfl'is'arranged' to be open at its upper and lower sides, andthe't'oothed wheels 1 land I? are arranged so that their lower edgesextend out of theo'pen lower side of the mounting space, whilev theupper surface of the toothed wheel. 12 extends outwardly through theopen upper side of the mounting space. The wheels ll and i3 arethereforepositioned so as to ride upon the upper surface of the rail 3, and

the desired guiding of the forward end of the machine is accomplished bya downwardlyprojecting guide lug 3%} formed respectively on the loweredge of the plate IQ and on the tubular portion 223, and a pair ofdownwardly projecting lugs 8i on the lower edge of theplate iZF. Thelugs 80 and 8! are thusdisposed so as toextend downwardly along.Opposite side edges of the rail R, and hence the tractive unit M ismaintained in the proper lateral relationfto the rail R and the wheel W.In supporting the toothed wheels? l, 12 and 13 in the desiredrelationship between the plates [2F and 'i'il, the toothed wheel H isinternally splined and is mounted on the splined portion 46A of thedrive shaft 40, the reduced end GQC of this shaft beingsupported in abearing sleeve 33 in the plate 56. The wheel ll is thus located near therear end of the tractive unit iii. and the toothed wheel 13 is supportedin spaced relation thereto and near the front of the unit it on a shaft84 that is embodied as atie bolt having a head 84A and a nut 8 13 so asto thereby afford additional means holding the mounting or hearingplates IEP and I8 together. The other a toothed wheel 12 is mounted on astub shaft 85 so that the ends of the shaft extend beyond the ends ofthe wheel 12 and are loosely supported in retaining pockets or bores 85,Fig. 3, formed in the bearing plates LZFand l0.

The arrangement of the toothed wheels ll, l2 and i3 is such in thepresent instance that the teeth of the wheel 12 rests upon. and mesheswith the teeth of the wheels H and i3 so that the wheel 1'2 acts as anidlenor transmitting connection between the wheel l3 andthewheel 5!.Thus when the shaft 60 is drivenin thedirecti-on indicated by the arrowin Fig. 4, so as to thereby advance the car pusher in a forward directon toward a wheel W, the wheel]??? will be similarly driven in such adirection as to also have a similar-forclri'ving action. the same timeand .as to such-forward advancing movement ward an incident .of the carpusher, the upper? toothed wheel "52 .is

driven in the opposite direction as indicated by the arrow on the wheel12" in Fig. 4, and hence when the exposed uppersur-face of the wheel'l2engages the tread of the-wheel W, it will-tend to impart forwardrollingznovement to the wheel-W as indicatedby the arrow applied to thewheel in Fig. 4.

Since the teeth of the several wheels H, 12 and 13 are in the presentinstance arranged to function both as powertransmitting gears and .as

fr ctiona slemsnt f d i me engaging the the reaction of the car wheel Wto pressjthe teeth offthefw'heel i2, downwardly into positive engagementwith theteeth'of the other wheelsll" and 13,," and hence the drivingconnection therebetweenjbecomes more positive as the: load in} creases.

In the use of the car pusher that is thus afforded, the device is placedin position on the rail Radjacent toa wheel W of a railway car that ist6 be moved, and is held in an upright position by means of therearwardly extending handle l8.

When the car pusher is thus positioned the wheels it and '13 support thefront end thereof on'the rail, while the roller l6 supports the rear endh thereof, and the lugs 83 and 8! serve to locate and guide the forwardend of the device in a lateral sense on the rail. The operator may thenactuate the switch lever 28A to start the motor 20, and the wheels H andI3 of the tractive unit will be started so as to advance the car pusherfor wardly toward the adjacent wheel W. The car pusher will thus advanceinto the" acute angular space between the railand the wheel, and if ithappens that the extension 22 is disposed on the innerside of the railso as to be aligned with the flange of the wheel W, it willbe'obse'rvedthat adequate clearances are afforded, aswill be evidentinFigs, 2 and 3.

As such forward movement of the car pusher progresses, the'to othedwheel l? will of course engage the tread of the wheel W, and when thisoccurs, the combined forward driving action of the wheels" l l and'lSandthe upwarddriving ac tion of the wheellZ on the car wheel W will'im partforward rolling movement to the car wheel W. The driving action is ofcourse continuous," and sincethe three toothed wheels 1!,12 and I3 arein effect wedged into" the angular space between the car wheel and therail by the forward driving action of the wheels H. and I3, thefrictionaldriving contact of the toothed wheels with the rail and thecar wheel becomes greater as the resistive load increases. Thus the carmoving operation of the present car'pus'her is eflicient insofar as thepower or force applying action is com cerned, and since the car pusherfollows the advancing movement of the car, the forward'movement of thecar is continuous, and repeated starting and stopping .of the cal-isavoided so'as'to eliminate waste of time and power.

Eroni the foregoing description it will be apparent that the presentinvention materially simplifies the. problem of pushing or movingrailway cars on sidings or the like, and since'the car pusherprovidedbythe" present invention is. portable in characterandi's poweroperated, the de sired carmovementsmay be attained without appreciablephysicalexertion'; The present invention providesifor a constantadvancing movement of thecar pusher asthe car rolls along the track,
